Benzyl chloride. Benzyl chloride, or Î±-chlorotoluene, is an organic compound with the formula C6H5CH2Cl. This colourless liquid is a reactive organochlorine compound that is a widely used chemical building block.
Two slits are illuminated with red light (Î» = 650 nm). The slits are 0.25 mm apart and the distance to the screen is 1.25 m. What fraction of the maximum intensity on the screen is the intensity measured at a distance 3.0 mm from the central.
The spacing of the fringes at a distance z from the slits is given by. For example, if two slits are separated by 0.5 mm (d), and are illuminated with a 0.6Î¼m wavelength laser (Î»), then at a distance of 1m (z), the spacing of the fringes will be 1.2 mm.
